The Effects of Microstructural Features on the Response of Aluminum Alloys to Cyclic Deformation.

Abstract

This program has been designed to isolate and determine the various parameters which control the mechanical behavior during monotonic and cyclic loading of alloys containing various microstructural features developed during the decomposition of 7XXX type aluminum alloys. In addition, limited studies of the stress-corrosion resistance and corrosion-fatigue resistance has been made. The primary goal has been to understand the fundamentals of the deformation processes involved in monotonic and cyclic loading. The results obtained from this study should lead to improvements in the properties of existing alloy systems through control of the microstructure and suggest ways of developing fatigue resistant age-hardenable aluminum alloys.
